The aim of the study is to present the issue of criminal liability of a court enforcement officer for submitting a false assets declaration. The author discusses both, the statutory features of a prohibited act under Article 233 § 6 of the Penal Code from the perspective of submitting assets declaration that is false in its content, and criminal law consequences of the aforementioned crime. In the author’s opinion, the current legislative solutions are excessively repressive. In particular, sanctions for submitting a false assets declaration by a court enforcement officer go further than the consequences of submitting a false assets declaration by the prime minister, minister or deputy minister. De lege ferenda, the author proposes the unification of criminal liability of public officials for providing false data in assets declaration.
